Payson is a gateway plugin that extends WooCommerce, allowing you to take payments via Payson. Payson cooperates with Visa, MasterCard and the Swedish online banks Swedbank, Handelsbanken, SEB and Nordea.
General information ↑ Back to top
When the order goes through, the user is taken to Payson to make a secure payment. No SSL certificate is required on your site. After payment the order is confirmed and the user is taken to the thank you page.
The Payson plugin acts as two separate payment methods, one for Payson Direct (credit card payment & online bank payment) and one for Payson Invoice.
In order to use the Payson gateway you need a Payson merchant account and also request a AgentID and a MD5-hash from Payson.
To utilize Payson Invoice you need to activate this feature in your Payson account. Contact Payson for further information about this.
Note that the plugin only works if the currency is set to Swedish Krona or Euros and the Base country is set to Sweden or Finland. To use the Payson Invoice feature, your store currency must be set to Swedish Krona.
Payson Direct ↑ Back to top
Direct Payments means that you easily can take credit card payments as well as direct payments via any of the associated banks.
Direct Payments supports Payson Guarantee (this can be turned on and off). Payson Guarantee means that the buyer will have the opportunity to inspect and approve or deny the merchandise before the payment is finally transferred to the seller.

The Payson gateway also offers Payson Invoice – let your customers receive their order first and pay by invoice later.

Testing ↑ Back to top
A separate test system is available that can be used to test your integration. It has the same functionality as the live API including IPN, but no real money will be moved. For bank and credit card payments a bank simulation page will be shown in place of the live bank page which allow you to simulate an OK or denied bank response.
When placing test orders you need to activate Test mode in the payment gateway settings and use the merchant and customer credentials displayed below.

FAQ ↑ Back to top
Q. When I try to Place order and proceed to the Payson payment window, I get this message:
{"result":"failure","messages":"","refresh":"false"}
What is wrong?
A. Most often this error appears because you are trying to make a purchase with the same email address as the registered Payson seller email. Payson interpret this as the seller and the buyer are the same person.
Q. I receive this error message when trying to order multiple items of one product:
array ( 0 => PaysonApiError::__set_state(array( 'errorId' => '590001', 'message' => 'The total amount specified for receivers does not match the total amount specified by the order items.', 'parameter' => 'orderItemList+receiverList', )), )
What is wrong?
A. This error concerns ONLY the Payson Invoice feature in the plugin. You need to have your shop set to “2” Number of Decimals to work properly with taxes and how they are calculated.
You will find the setting here: WooCommerce –> Settings –> Generell –> Number of Decimals
If you do not want to show decimals in your prices to your customers we recommend you to use this snippet in your functions.php file or in a separate plugin:
/**
* Trim zeros in price decimals
**/
add_filter( 'woocommerce_price_trim_zeros', '__return_true' );
